Solution

1. Preparation

Gather tools and parts needed for repairs.
Disconnect the negative battery terminal to prevent electrical shorts during repairs.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Addressing Fault Codes

Sub-step 1: Refer to the OBD-II scanner to identify and document the fault codes.
Sub-step 2: Research the fault codes to determine the affected systems or components (e.g., oxygen sensor, mass airflow sensor).
Sub-step 3: If the code indicates a sensor issue, proceed to replace the faulty sensor as necessary.

3. Repairing or Replacing Components

Sub-step 1: For a faulty gas cap, replace it with a new OEM cap to ensure proper sealing.
Sub-step 2: If vacuum leaks are found, replace damaged hoses.
Sub-step 3: For electrical issues, repair or replace damaged connectors or wiring.
Sub-step 4: If engine performance issues are detected, perform a tune-up (replace spark plugs, air filter, etc.).

4. Resetting Check Engine Light

Sub-step 1: Reconnect the negative battery terminal.
Sub-step 2: Use the OBD-II scanner to clear the stored trouble codes.
Sub-step 3: Start the vehicle and monitor the check engine light to ensure it remains off.
